Used primarily as methyl esters in biodiesel production, providing a renewable fuel source that can replace or blend with diesel fuel. These esters offer good combustion properties and are derived from natural fats and oils, making them biodegradable and less harmful to the environment. Also utilized as intermediates in the production of surfactants, lubricants, and emulsifiers for use in soaps, detergents, and personal care products. Their ester structure allows for easy modification in chemical synthesis, supporting applications in industrial lubricants and metalworking fluids. Additionally, they serve as extractants in separation processes and as carriers in pesticide formulations due to their solvency and low volatility.
